Answer:
d
Step-by-step explanation:
inverse property of addition is going back to zero with the equation so adding 2 to negative 2 will go back to zero
To find this answer, we need to multiply 3.57 by 12.

Therefore, 12 planks will cost $42.84.
Answer:
7/18
Step-by-step explanation:
21 out of 54 = 21/54 = 7/18
Ist amount paid = $1500
Making $350 for 10 months = 10*350 = $3500
Total amount paid = 1500 + 3500 = 5000
So an amount of $5000 was paid to cover the cost of $4500 within the ten month period.
I = PRT
Interest, I = 5000 - 4500 = 500Time, t = 10 months = 10/12 = (5/6) year.Principal P = 4500
R = I /(PT) R = 500 / (4500*5/6)
R = (500*6) / (4500*5)
R = 0.1333..
R ≈ 13.33 % per annum.
Umm, I need the numbers that are given but I can give you examples. It can be 5 1/6 or like 5 4/9
The whole number needs to be bigger
